This file contains the USB endpoint 0 management routines corresponding to the standard enumeration process (refer to chapter 9 of the USB specification. This file calls routines of the usb_specific_request.c file for non-standard request management. The enumeration parameters (descriptor tables) are contained in the usb_descriptors.c file. More...

void usb_process_request | ( | void | ) |
usb_process_request.
This function reads the SETUP request sent to the default control endpoint and calls the appropriate function. When exiting of the usb_read_request function, the device is ready to manage the next request.
< un-supported request => call to user read request
